Hultgren, Bridgeport, Conn. Filed July 2t), 1960, Ser. No. 44,197 Claims. (Cl. 20o-56) The present invention relates to an all plastic lipstick case having means for facilitating the movement of the lipstick therein from a retracted to a projected position.

It is an object of the present invention to provide an all plastic lipstick case which is simple to manufacture, easy to assemble and operate, and relatively inexpensive.

Another object of the invention is to provide means on the inner casing for venting the inner casing to permit a uniform free movement of the lipstick and carrier in the inner casing.

These objects are accomplished by making the lipstick casing from three molded parts, each formed of'plastic material. The inner part in which a lipstick carrier is mounted for sliding movement is provided with means cooperating with an o-uter sleeve for moving the lipstick sidered in connection with the accompanying drawings in which: FIGURE l shows a longitudinal sectional View of the "device with the lipstick in dot and dash lines.

States Patent O fice 2 with a plastic sleeve 22 which is adapted to be mounted on the inner member solely for rotation with respect 'thereto and which is provided on its inner surface with a spiral groove 23 into which the end of the button on the carrier projects. It will be seen that by relatively rotating the sleeve on the inner member the button will be caused to move out of the bottom side passage Ztl and into and along the longitudinal passage to project the lipstick, and at the completion of the projecting movement the button moves into the other lateral passage 2l to hold it in projected position. The sleeve is located on the inner member by having its lower end engage an abutment llapprefaV erably of a depth equalto the thickness of the sleeve,

FIG. 2 is a view of the inner casing with the outer l N sleeve shown in section. l

FIG. 3 is a side view 'of the inner casing showing the venting panel.

FIG. 4 is atop view oli-FIG. 1 without thelipstick.

FIG. 5 is a sectional view taken along kline S-S of FIG. l with the lipstick in position. 1

As shown in the drawings, an inner casing comprises a cylindrical member ll molded of plastic material and having a transverse wall 12 at one end closing the member. The other end of thecylindrical member is open and is adapted to have a lipstick 13 (shown in dot and dash lines in FIG. l) projected therefromor retracted within the casing. i

In order to project the lipstick, a carrier 14 is provided which is slidably mounted within the cylindrical member. Preferably, the carrier is a molded onepiece cup-shaped element `15 having ribs 16 formed its inner wall adapted to bite into a lipstick as it is inserted in the carrier, as shown in FIG. 5, to prevent relative rotation between the lipstickrand carrier. The bottom of the carrier is provided'with an aperture 17 or vent to permit air to be expelled from the cup as the lipstick is pressed therein. Projecting from one side of the carrier is a button 1S which is adapted to pass through a longitudinally extending slot 19Vformed in the side wall of the inner member 1'1. As shown in FIG. 2, the slot extends from point spaced inwardly from the closed end and extends longitudinally along the member to the `free end of the member. The inner end ofthe slot is provided with a lateral passage 20 into which the button is moved in the innermost position of the carrier and is held against inadvertent longitudinal movement. The slot adjacent the other end is provided with a lateral passage 21 extending from the opposite wall of the longitudinal slot and into which the button is moved in its projected positionto prevent inadvertent retrograde movement of the lipstick from projected position.

In order to move the carrier from retracted to projected position, the device of the present invention is provided formed on the inner member and is held against the abutment by having an annular recess 24 formed on the inner surfaceat its outer end adapted to receive a projection or rim 25 on the end of the inner member. The edge of the rim is beveled at 26 to facilitate assembly of the device.

The cup-shaped carrier slidably engages the inner wall of the inner member 11 as it moves along and is stabilized against tilting movement. In order to facilitate its movement, the inner wall is provided with a venting panel 27 which extends for a substantial length along the wall intermediate the end.

The panel, as herein illustrated, comprises a plurality of square openings 2S extending through the wall of the Vinner member opposite the slot therein, While. the openings may be of any shape, 'such as round, oval or the like and can be arranged in any particular pattern, in the herein illustrated form of the invention the'square openings are arranged in a rectangular panel to provide for uniform andl adequate venting of the inner member as the carrier and lipstick are moved therealong, the venting panel permitting oil blisters, which usually develop because of the high oil content of many lipstick formulations, to evaporate and prevent uncontrolled slipping therebetween.

The bottom of the inner member may be provided with knurlingor other linger-engaging means 29 for facilitating the rotation of the inner member with respect to the sleeve which can be held in the lingers.

The device'l of the present invention can be `readily molded from plastic material and the three elements thereof can be quickly and easily assembled. ln assembling the device, the carrier 14- is inserted into the interior of the inner member with the button passing through the open end of the slot 19. After the button on the carrier has been moved to the bottom ofthe slot, the sleeve is passed over the end of the inner member. The beveled edge 26 and the resiliency of the material and the opening of the slot at the end of the inner member causes suficient contraction or the projection 25 at the end of the inner member to enable the sleeve to be passed in the position of FIGS. l and 2 in which the projection snaps into the annular groove 24 in the sleeve and locks itin position against longitudinal movement but permits relative rotation betweenthe sleeve and inner member.

The spiral groove 23 inthe sleeve extends from the bottom of the sleeve and, as shown in FIG. 2, terminates at a point coinciding with the upper edge of the lateral passage 21 so that as the sleeve is putin position the inner end can receive the button iS and move into cooperative relation therewith for moving the button longitudinally of the slot 19 and into the proper lateral passages Ztl, 2.1 in response to relative rotation of the sleeve on the inner member.

With the sleeve in position, the elements are electively locked together against separation. The carrier can be moved to its outer position and the lipstick can be readily inserted therein for retraction and projection by the carrier. The movement of the carrier in the inner member is greatly facilitated by the novel venting panel 27 disposed opposite the slot 19. p

A After the lipstick has been inserted in the carrier and moved to retracted position, `a usual cover "(.not shownl' may be positioned over'the'casing.V

Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.
